    Enhanced Spacer Length between Mannose Mimicking Shikimoyl and Quinoyl Headgroups and Hydrophobic Region of Cationic Amphiphile Increases Efficiency of Dendritic Cell Based DNA Vaccination: A Structure–Activity Investigation
    摘要:
    In the field of dendritic cell based genetic immunization, previously we showed that liposomes of cationic amphiphiles containing mannose-mimicking shikimoyl headgroup are promising DNA vaccine carriers for dendritic cell (DC) transfection. The present structure activity study reports on the influence of spacer length (between mannose-mimicking headgroups and quaternary nitrogen centers) in modulating the DC-transfection efficiencies. Further, we report on the anti melanoma immune response inducing properties of the promising cationic amphiphiles in syngeneic CS7BL/6J mice under prophylactic settings.

  • β-Directing Effect of Electron-Withdrawing Groups at <i>O</i>-3, <i>O</i>-4, and <i>O</i>-6 Positions and α-Directing Effect by Remote Participation of 3-<i>O</i>-Acyl and 6-<i>O</i>-Acetyl Groups of Donors in Mannopyranosylations

    isolation of a stable bicyclic trichlorooxazine ring resulting from the intramolecular trapping of the anomeric oxocarbenium ion by 3-O-trichloroacetimidoyl group provided evidence for this remote participation. The triflate anion, counteranion of the mannosyl oxocarbenium ion, was essential for the beta-selectivity, and covalent alpha-mannosyl triflates with an electron-withdrawing group at O-3, O-4
    发现在 O-3、O-4 或 O-6 位具有吸电子的邻三氟甲基苯磺酰基、苄基磺酰基、对硝基苯甲酰基、苯甲酰基或乙酰基的各种受体的甘露糖基化被发现是 β 选择性的,除非供体具有 3-O-酰基和 6-O-乙酰基,主要产物为 α-甘露糖苷。3-O-酰基和 6-O-乙酰基的 α 导向作用归因于它们的远程参与,以及由 3-O-三氯乙亚胺酰基对异头氧代碳鎓离子的分子内捕获所产生的稳定双环三氯恶嗪环的分离小组为这种远程参与提供了证据。三氟甲磺酸盐阴离子,甘露糖基氧代碳鎓离子的抗衡阴离子,对β-选择性至关重要,共价α-甘露糖基三氟甲磺酸盐在O-3处具有吸电子基团,O-4或O-6通过低温NMR检测。强吸电子磺酰基在甘露糖基化中表现出更高的β-导向效应,使α-甘露糖基三氟甲磺酸酯比弱吸电子酰基更稳定。因此,我们提出了 β-甘露糖基化的机制和 β 导向效应的起源:吸电子基团将稳定 α-甘露糖基三氟甲磺酸酯中间体,以及

    作者:Mickaëlle Brard、Céline Lainé,、Gildas Réthoré,、Isabelle Laurent、Cécile Neveu、Loïc Lemiègre、Thierry Benvegnu
    DOI:10.1021/jo071181r
    日期:2007.10.1
    A synthetic route for the preparation of symmetrical and unsymmetrical archaeal tetraether-like analogues has been described. The syntheses are based upon the elaboration of hemimacrocyclic tetraether lipid cores from versatile building blocks followed by simultaneous or sequential introduction of polar head groups. Functionalizations of the tetraether lipids with neutral lactose or phosphatidylcholine
    已经描述了用于制备对称和不对称的古细菌四醚样类似物的合成途径。合成是基于从通用构件中精心修饰的半大环四醚脂质核心,然后同时或相继引入极性头基。设想了具有中性乳糖或磷脂酰胆碱极性头和阳离子甘氨酸甜菜碱部分的四醚脂质的功能化,既可以增加膜的稳定性,又可以表现出与带电核酸的相互作用。另外,还有效地合成了甘露糖和乳糖三天线簇,其被设计为用于与凝集素型受体选择性相互作用的多价配体。
  • Acid-catalysed rearrangement of glycosyl trichloroacetimidates: a novel route to glycosylamines
    作者:Kim Larsen、Carl Erik Olsen、Mohammed Saddik Motawia

    日期:2008.2
    novel route to glycosylamines has been developed. Treatment of glycosyl trichloroacetimidates with TMSOTf under glycosylation conditions, but in the absence of an acceptor, resulted in complete rearrangement of the trichloroacetimidates into the corresponding N-protected-glycosylamines. Reductive cleavage of the trichloroacetyl groups using sodium borohydride provided the desired glycosylamine products
